Goldie’s AP® Computer Science Principles – Unit 2 Digital Information

AP® Computer Science Principles

Unit 2 – Digital Information

Complete Unit Plans

This unit was designed to save your most precious resource: YOUR TIME! In this complete unit, you will have everything you need to teach, support, and assess your students on everything involving digital data, binary, hexadecimal, digital representations of images, sound, and text, and working with data in Google Sheets, in the AP® Computer Science Principles course.

This unit is part of my larger curriculum bundle: Goldie’s FULL CURRICULUM for AP® CSP

This resource contains the following:

• Student guided notes (7 lessons) with a teacher answer key
• Activity: Conversion Circuit
• Teacher PowerPoint slides to accompany each lesson
• 4 homework assignments with answer keys
• 1 Unit Project
• 2 Multiple Choice Assessments with an answer key
• Jeopardy-Style Review Game

All of the resources are 100% editable, so you are able to modify to fit your classroom needs. The zip folder includes all the Word documents for the resources, which you have permission to edit. The PDF version and answer keys are included for your convenience.

I teach this course without a textbook, so everything that is provided here, can be used without supplementation. The only thing I use in my class that is NOT included in this content is the secured AP® exam questions.
